IMPROVEMENT IN WAT E R-WHEELS.

-The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern: I

Be it known that I, FREDERICK G. GOGGIN, of Burlington, inthe county of Chittenden and State of Vermont, have invented a new and useful Improve,-

.nient lin Water-Wheels; and I do; hereby declare. that the following is a full, clear, and exactr-ilescrip tion thereof, which will enable others skilled in the art to make and usethe same, reference being had' to the accompanying drawing forming-part 0i' this specification, in whiehy Y l Figure 1v is a sectional horizontal sect-ion of my invention1 x x, fig. 2, being the section line.,

Figure 2 is a detail vertical section of thc same, y y, iig. 1, being the section lineal -I'= v Similar' letters .of refercnceindicate corresponding parts. I'

The object of thisinvention is improvement. in water-wheels of that class in which gates are pivoted between chutes which guide the water to the buckets. v lhe inventioufconsistsy in pivoting tli'e gates, near their inner ends, to the base-plate and cover of the wheel-cas e, and at the other ends, to a sliding-ring, and 1n attaching the straight chutes firmly to said ring.

The object of this peculiar arrangement is, mainly,

to avoid moving the ring the distance required in` other wheels of a generally analogous construction, the chutes and gates in my invention being moved simultaneously. o

A A, in the drawing, are sections of the cover and base-plates of the stationary wheel-case.

B B are mcvablevannular. plates or rings, placed with their inner edges against the circular outer edges of the plates A-A, respectively, and connected .with eachother so that they can be turned together on the case.

G C ,are the straight or curvilinear chutes', east to or otherwise rigidly united with the inner faces of the plates B, and extending over the faces f the 'plates operate as specified.

A, as shown, so that their inner ends are about in line with'the inner edges of the plates A. f

D D are the gates, pivoted by pinspa a totl stationary plates A, butV reaclng with `their heels over the lower plate- B, as shown.

The heel of each gate rests against a chute, and is held 'in -contact therewith by a pin, b,t projecting from the platel B, as shown.` When, by suitable pinion or other mechanism, the rings 1? are turned, the chutes are carried along with the same, 'and servefin connectionwith the pins Y), to swing tlle-Y gates on their stationary pivots a, and to thereby regulate the width of the Water veins. 'The chutes and gates move thereby simultaneously.

I am aware that wheels have already beenin use with movable gates that are controlled by slidingrings, but in the same the chutes were fixed to the I and opened or closed by the motion of the chutes; y'

the gates were only moved to 'adj ust the size ofvein, while in my wheel the chut-es and gates move simultaneous, so that 'but half the ordinary motion of the rings is required. l

The pins b may be dispensed with, as the pressure of the water will always hold the vheels of the gates in contact with the' chutes; they are useful merely in case the gates become clogged aud stick. p

Having thus described my invention,

I claim as new and desireto secure by Letters Patent- The straight vertical chutes C C, xedly attached to the ring b, and the gates D, pivoted, respectively, to the ring D and base-plate and cover of the wheelcase, in the manner shown and described, so as to Witnesses: l".
